Glee’s Walking Machine: Fact and Fiction

As a loyal devotee of Glee, I was stunned to see the the ReWalk exoskeleton featured in last night’s climactic scene. I won’t get into the plot details, but basically the ReWalk functions as a Christmas miracle, letting Artie walk again, albeit in a limited way.

Even more surprising than the inclusion of this rather arcane technology is the fact that the show’s description of if was entirely accurate. (This is, after all, a rather fantastical show.) They got the name right, and the fact that it’s been developed in Israel. And, true to life, the machine doesn’t let Artie just hop around. In order to use it, he has to press an arm-mounted keypad, and then take tentative steps one at a time. But by golly, he’s actually up and moving!

The most unrealistic aspect of the presentation was that, a) you can’t just buy a ReWalk yet; to use one you’d need to be enrolled in a clinical trial, of which there’s only one in the US, near Philadelphia b) it takes a fair bit of training to master.

UPDATE: With just a few days of shopping left before Christmas, word comes that ReWalk has been approved for sale by the FDA. Not for home use, as seen in Glee, but for use by patients in clinics and hospitals. “The ReWalk system will be available for sale as of January, for institutional use only,” says Heather Newcomb, Director of Communications at the Albert Einstein Healthcare Network near Philadelpha. “The cost will be around $85,000.” So even though no one will be finding one under their Christmas tree, a lot more people with spinal-cord injury will have a chance to ambulate again.

Here’s some video I took in January of one of the patients in the clinical trial, a man named Floyd Morrow:

And here’s a link to the story I wrote in Parade.

Black Friday: The Stampede

Crazy video, via Mark Frauenfelder at Boing Boing, of Xmas shoppers trampling each other to get at Black Friday bargains at 4am.

Not a proud moment for humanity. But as I’ve written before, this kind of crowd dynamic isn’t unique to the US; in 19th century Russia 1389 people died at a coronation ceremony for Tsar Alexander II of Russia when a rumor circulated through the crowd that souvenirs were in short supply, causing people to rush forward en masse.

An Accident Strikes, and the World Becomes Smaller

There’s a wonderfully insightful piece in the New York Times today by science writer Gina Kolata, who describes a cycling accident in which she ran into another rider, fell off her bike, and broke her collar bone. The injury was not crippling – she managed to ride another 90 miles that same day – but the psychological ramifications were long-lasting, as the accident made her realize how vulnerable she really was when riding a bicycle. All at once, an activity that had long given her joy became a source of fear. An important part of her life was shut off.

As I’ve written before, the two main tools that we possess to control fear are information and a sense of control. In Kolata’s case, she realized that the sense of control that she had once felt while riding her bike was illusory. Stripped of her sense of control, she was helpless against her fear. She just couldn’t get back on the bike, at least for a while.

“Control makes a big difference in whether we take risks,” [Carnegie Mellon] professor of economics] Dr. Loewenstein said. “With biking, you feel in control until you have an accident. Then all of a sudden you realize you are not in control. That can have a dramatic effect — you can shift abruptly from excessive daring to exaggerated caution.”

I’m currently working on a story for Psychology Today about why some people are mentally tougher in the face of crisis than others, and what the rest of us can learn from them. A major lesson I’ve taken away from my research is that the way we choose to think about our struggles is a critical factor in resilience. Those who bounce back easiest are those who can think of a negative outcome as a challenge rather than a defeat, and recognize in each setback an opportunity to grow and test themselves.

In Kolata’s case, she was not able to take such an upbeat stance. She had come to feel that when she was on a bicycle, something bad could happen to her at any time, and there was nothing she could do about it. Yet at the same time she continued to run, even though that activity poses an even greater risk of injury. Why? Continue reading An Accident Strikes, and the World Becomes Smaller

Caught in a Stampede, What Would You Do?

Once again, a stampede has turned a large celebration into a tragedy. Just four months after 21 people died at the Love Parade in Duisburg, Germany, more than 350 were killed and a similar number injured yesterday at a festival in Cambodia. The terrible irony of stampedes is that for decades engineers and sociologists have been studying how to design spaces so that crowds don’t turn deadly, yet the number of incidents only continues to grow. As I pointed out recently, there were only 24 such tragedies around the world in the 1980s; in the last decade, there have been well over 100.

Part of the problem is likely that growing affluence around the world, together with improved communication and transportation, means that it’s easier for large crowds to assemble. But another factor may be that the general public has erroneous ideas about what a stampede actually looks like, how it can turn deadly, and what one can do should one occur. Maybe if more people were aware of what a potentially dangerous situation looked like, they could take steps to defuse it. So: what does a real-life stampede look like?

Security Guru Bruce Schneier: "I Predicted TSA Brouhaha"

I’ve got a post up today on the Popular Mechanics website with an interview I conducted yesterday with cryptology expert and security consultant Bruce Schneier, who since 9/11 has been one of the most pointed critics of the government’s anti-terrorism security programs. In his 2003 book Beyond Fear he coined the phrase “security theater” to refer to measures which are undertaken not because they will be effective at thwarting attacks, but because the agencies carrying them out need to appear to be doing something useful. I asked Schneier about the recent controversy involving the Transport Security Agency’s use of invasive scanners and full-body pat-downs. You can read the full interview here. Here’s the transcript: Continue reading Security Guru Bruce Schneier: "I Predicted TSA Brouhaha"

7 Essential Steps to Mastering Temptation

We Americans are out of control. We want to lose weight, but we can’t stop eating. (Since 1980 the obesity rate in the United States has doubled; two-thirds of the population is now overweight.) We want to save, but we can’t stop spending. (The average American household owes more in debt than it earns in a year, and still keeps spending more than it takes in.) We want to be healthy, but we can’t stop smoking, drinking, and doing drugs. (One in ten Americans has an addiction disorder.) We can’t even control our attention. (We’re multitasking like never before, constantly switching our focus from Blackberries to iPhones, to email and texts and the internet.)

These behavioral problems aren’t just vexing and embarrassing. They’re killing us.  Smoking and obesity are the top two causes of preventable death in the United States. More than half of people who die between the ages of 15 to 64 do as a result of unhealthy decisions, compared to just 5 percent a century ago. And impulse control takes a toll across all age groups. Children born today might be the first in American history to have a shorter life expectancy than their parents. They will also face greatly diminished economic prospects, as runaway spending in both private and public spheres contributes to an unprecedented and increasingly unsustainable debt load.

Self-control is one of the hardest things to achieve in modern life, but in the course of my research I’ve come across seven key tools that can help us to resist temptation. Continue reading 7 Essential Steps to Mastering Temptation

The 2 Key Parenting Skills You Didn’t Know About

We all know that the most important thing in raising a child is to offer it unstinting love. But what are the next two most important things? Surprisingly, neither have to do with how you specifically relate to your child, as I learned from a fascinating article in the current issue of Scientific American Mind by child psychologist (and fellow PT blogger) Robert Epstein.

Epstein points out that parents are deluged with advice — there are more than 40,000 books on the topic listed on Amazon. So he and his colleagues set out to see if they could determine which techniques were the most important in raising healthy, happy, successful children. Epstein analyzed responses to an online parenting-skills questionnaire that had been completed by some 2000 people. The survey asked respondents to rate themselves in 10 different categories of parenting skill, which Epstein calls “The Parents’ Ten,” since prior studies have shown them to be crucial tools. The test-takers were also asked how well their children had turned out.

As expected, Epstein found that the most important parenting skill is simply love them. “Our… findings confirmed what most parents already believe,” Epstein writes, “that the best thing we can do for our children is to give them lots of love and affection.” But the second and third most important factors related not to how the parents treat the child, but one another and themselves.

Yes, You Really Can Lift a Car Off a Trapped Child

This month’s issue of Psychology Today includes my article “Stealth Superpowers,” about how the brain’s automatic fear-response systems can unleash hidden mental and physical abilities. A portion of the article is now online on the magazine’s website. The excerpt tells the story of Tom Boyle, Jr, a man who quite suddenly and unexpectedly found himself in the middle of a life-or-death drama:

“Oh God, do you see that?” his wife said.

Boyle saw it: the crumpled frame of a bike under the car’s bumper, and tangled within it a boy, trapped. That’s when Boyle got out and started running. For an agonizing eternity the Camaro screeched on, dragging the mass under it. As it slowed to a stop he could hear the bicyclist pounding on the car with his free hand, screaming. Without hesitating Boyle bent down, grabbed the bottom of the chassis, and lifted with everything he had. Slowly, the car’s frame rose a few inches. The bicyclist screamed for him to keep lifting. Boyle strained. “It’s off me!” the boy yelled. Someone pulled him free, and Boyle let the car back down.

As I write in the story, Boyle accomplished an almost unthinkable feat of strength. The world record for dead-lifting a barbell is 1,003 pounds. A stock Camaro weighs 3000 pounds. So how did Boyle pull it off? Here’s how I explain it in the story: Continue reading Yes, You Really Can Lift a Car Off a Trapped Child

Getting Lost, and Loving It

The most exciting thing about travel for me is the delicious sense of disorientation, that Alice-in-Wonderland sense that even the smallest, most mundane details of life have been switched around. For me, getting lost in a strange place isn’t necessarily a bad thing at all. I like the sense of being totally cut off from the predictable world of my everyday life, immersed in the strangeness of the new. In the current issue of Travel + Leisure magazine, I have a short article talking about how traveling without navigational aids can boost your awareness of the world around you.

As it happens, a friend of mine, the travel writer Matt Gross, has been thinking along the same lines. Matt spent years traveling around the world writing the Frugal Traveler column for the New York Times. Now he’s started a new column called “Getting Lost,” in which he describes his attempts to deliberately disorient himself in places around the world that he has never visited before. Given our mutual interest in the topic, we decided to interview each other. My answers to Matt’s questions can be found over at his website, The Minor Glories.

Most of us try hard not to get lost. Where did you get the idea to deliberately throw yourself into the experience? Continue reading Getting Lost, and Loving It

The Scary Science of Halloween Haunting

To quote Glee‘s Sue Sylvester: “It’s time to get back to the real meaning of Halloween. Fear.”

This is the time of year when all of us — rich and poor, young and old, living and undead — can put aside our differences and celebrate the sheer joy of having the wits scared out of us. Most of the time, we do our best to avoid fear, so it’s nice that once a year society can acknowledge the pleasure of terror. Of course, for the scientifically minded, this inevitably raises the question: just how scary is scary?

Two years ago, Michigan cardiologist Nathan Foster decided to find out. Continue reading The Scary Science of Halloween Haunting
